Functioning and various information
Function of a starter motor on Lexus RX
The starter motor is an electric motor whose only function is to start the engine of your car. By a magnetic system and a “serial” technology, it will launch an enormous torque that will allow it to drive the pistons of the engine that are subjected to enormous compression and an oil that provides additional resistance being not very fluid when cold.
It is completed by the “solenoid”. It is an electromagnet that goes under a 12 volt electric impulse to push the fork (link part between the “solenoid” and the electric motor of the starter) and thus engage the starter drive pinion on the engine flywheel. Following this action, once in engagement, the starter motor of your Lexus RX is activated and turns the drive pinion on the flywheel to start the engine.

- Do not try to start your engine for too long
- Do not use a starter motor on Lexus RX with a tired battery
Even if your engine does not start because of tired glow plugs, for example, or because the weather conditions is too cold. You should not try to start for more than a few seconds or you will burn your starter motor.
Although when you have a battery that is tired, you always want to start your car, the energy it is capable of holding may not be good enough to give the power required by the starter motor to start your engine. Repeated attempts will pre-use your starter motor and if you do not solve the cause of your failure to start repeatedly, your starter may be the future part you will have to swap.
